An electrochemical analyte sensor having conductive traces on a substrate is used to determine a level of analyte in in vitro or in vivo analyte-containing fluids. The electrochemical analyte sensor includes a substrate and conductive material disposed on the substrate, the conductive material forming a working electrode. In some sensors, the conductive material is disposed in recessed channels formed in a surface of the sensor. An electron transfer agent and/or catalyst may be provided to facilitate the electrolysis of the analyte or of a second compound whose level depends on the level of the analyte. A potential is formed between the working electrode and a reference electrode or counter/reference electrode and the resulting current is a function of the concentration of the analyte in the fluid.

An electrochemical sensor comprising:a flexible, planar substrate; a first conductive material non-leachably disposed on a first surface of the planar substrate to form one or more working electrodes; one or more contact pads on the first surface and in electrical contact with the one or more wor
1. An electrochemical sensor comprising:a flexible, planar substrate; a first conductive material non-leachably disposed on a first surface of the planar substrate to form one or more working electrodes; one or more contact pads on the first surface and in electrical contact with the one or more working electrodes; a second conductive material non-leachably disposed on one of the first surface and a second surface of the planar substrate to form a counter electrode, a reference electrode, or a counter-reference electrode; a contact pad disposed on the one of the first surface and the second surface and in electrical contact with the counter electrode, reference electrode or counter-reference electrode; an enzyme non-leachably disposed proximate to the working electrode; and an analyte mass transport limiting layer disposed over at least a portion of the working electrode to limit transport of an analyte to the working electrode; wherein the sensor comprises a wide portion and a narrow portion, the narrow portion having a length of 2 cm or less and a width of 2 mm or less, and the narrow portion configured and arranged for subcutaneous implantation into the body of an animal for contact with body fluid of the animal.
